Improvement of the transducer makes it possible to get a flat characteristic. A special feature of this loudspeaker is its very sharp directivity pattern, which makes it possible to realize a sound spotlight. 展开 关键词: Loudspeakers Acoustic waves Acoustical properties Sound pressure Sound sound ...
Avoid echoes: rooms with carpets, blankets and soft furniture absorb sound waves better and will reduce echoing coming from the hard surfaces around. Also, small spaces echo less than bigger ones. You'll sometimes see advice to make your recording in a closet or cupboard: a small space with...

allowing a sound wave oscillation device to be mounted to a furnace wall without a mounting limit even in the furnace wall in a state of a high thermal load, in the same way as the furnace wall in a state of a low thermal load, and capable of preventing noise from leaking to the ...
Moreover, the sound of rain, a type of pink noise, will make us feel sleepy too. Like white noise includes all the sound frequencies 频率)humans can hear, but it has fewer high frequencies. This makes pink noise sound softer. Studies show that people's brain waves(脑电波) will they h...
identical pitches are played at once (like voices in a choir), the chorus effect has slowly taken a little bit of a life of its own, morphing into a “character” effect that adds a liquid quality to any sound, and that’s particularly effective in “opening up” mono sounds in stereo...
